Caching Realm: General

Use this page to configure the Caching realm. The Caching realm works
with the File realm, alternate security realms, or custom security realms
to fulfill client requests with the proper authentication and
authorization. The Caching realm manages separate caches for users,
groups, permissions, access control lists (ACLs), and authentication
requests. To use the Caching realm, you need to use Compatibility
security. The use of the Caching realm is deprecated in this release of
WebLogic Server.
